is the specified Index Field "N1" a text field or a numeric field? If it is a text field, the current behaviour would be correct.
To achieve what you want, you should create a global Variable (Numeric), then in the first "assign data" step, convert the value from the text index field to a numeric value and store it in the global variable. To accomplish this, use an arithmetic expression, for example: CInt(DW_N1)
In the condition, you may then use the GV instead of the index field. Your desired logic should work then.
Hope this helps.
